BRUSH.

SPECIFICATION forming part of Letters Patent No. 240,103, dated April12, 1881.

Application filed February 18, 1881.

(Model.)

To all 'whom fit may concern Beit known that I, JAMES M. DENNIS, ofCambridge City, in the county ot Vayne and State of' Indiana, haveinvented a new and Improved Varnish-Brush, of which the following -is afull, clear, and exact description.

Figure l is a perspective view of' my wooden varnish or pain-t brush,and 2 is a sectional view of the same.

1o Similar letters of reference indicate corresponding parts.

Theinventiou consistsin the process of separating and preparing woodyfiber for varnish or paint brushes, as hereinafter described.

In carrying my invention into effect l add to about eight ounces ofwater two ounces ot concentrated alkali and then soak the pieces of woodor bark'of suitable size in the boiling solution for about ten minutes,and then I subzo ject the wood or bark to a crushing, pressing,orpouuding process, which separates the fibers from each other and fromthe nou-tibrous pou tion. and then I wash the wood or fibers in cleanwater, then dry the saine. I then boil the pieces of wood in waterhaving a quantity of glue added, for about one-half hour, and tinallyoil the fibers with olive or other oil to render them elastic.

In making the character ot' brush shown iu 3o the drawings, in which thefilamentous portion a, the body I), and the handle c are all formed Yot'a single piece of' wood, the piece of wood out of' which the brush is tobe formed is given the proper shape and outline by turning, shaving, orotherwise, and only the portion a is subjected to the treatment abovedescribed, and then the Wrapper c is secured to the body b, to preventbreaking and further separating of' the fibers by the nails or screws d.

Instead ot' forming the handle e of' the brush 4o before the treatmentfor separating the fibers, it is obvious this may be done at'ter suchtreatment, it" desired; and instead of forming the entire bruslr of asingle piece otwood or inner bark, the fibers may be obtained separatelyby treating, as above described, pieces ot' the Wood or bark ot'suitable size to make the requisite length otl fibers, and subsequentlysecuring the fibers to the handle or body of the brush, by gluing orotherwise, in which case the han- 5o dle and body may be of any wood ormaterial.

Haring thus described my invention, I claim as new and desire to secureby Letters Patent- The process herein described for preparing the fibersof' wood in or for t-he manufacture of brushes, which consists in firstsoaking the wood in heated alkaline water, then separating the fibers bypressing and pounding, or otherwise` then cleaning the fibers, thenboil- 6o ing the same in agglutina ted water, and finally oiliug thefibers, substantially as and for the purposes described.
